Bently Nevada 3500/32M 149986-02 Spare 4-Channel Relay Control Module
A full-height front control module providing 4 independently programmable relay channels in the 3500/32M 4-Channel Relay Module platform.
Key Information
3500/32M 149986-02 is the Bently Nevada spare 4-channel relay control module for the 3500/32M 4-Channel Relay Module. It serves as the full-height front control module in the relay assembly.
Front control module with OK, TX/RX and channel alarm indication. The complete part number must be matched with the correct companion module, channel configuration and field-wiring duty.
Functions
- Supports 4 independently programmable relay channels.
- Alarm Drive Logic with AND/OR voting using rack monitor conditions.
- Uses controls single-pole double-throw (spdt) relay outputs.
- Fits the documented full-height front control module position in a 3500 rack.
- Maintains the relay assembly’s exact control/output-module pairing.
